Error saving in Word 2000

[Anthony]

Hello,

I am receiving a error while trying to save documents in
word 2000. The error message I'm receiving is:
"Word cannot complete the save due to a file permission
error"

If I use a different PC and log in as the same user, I am
able to make changes and save the document.

All the PCs in our office are running Windows NT 4.0 with
Service Pack 6a

Any ideas?

Thanks,
